I work as a server afterschool for 15-20 hours a week in a busy restaurant in downtown Toronto.
These last few weeks, the restaurant manager has been assigning me shifts alone (managing the sit-down and take-out alone without any other servers or manager there) for relatively quieter days. She has also given me an extra manager card (which I can use to correct transactions, void purchases, etc.) and other duties of a manager (training some new servers on the shift, interacting with Uber eats, correcting the inventory on our register and the delivery apps, opening and closing the store, etc.).
Although I’m not technically a shift manager, I do have a leadership role there and do many duties of a manager. At my restaurant, we don’t have specific shift managers because generally the restaurant manager is there almost always. How could I translate that into a title/short description to show colleges on my application? Is it unethical to write shift manager as my role?
